(54) | Connecting structure between fluid device and joint |
(57) The connecting structure between a fluid device and a joint according to the invention
is a connecting structure between a fluid device and a joint in which a peripheral
portion 3 of a fluid supply/discharge passage 1 in a fluid device P, and a fluid joint
T are fittingly coupled to each other, whereby the fluid supply/discharge passage
1 and a passage 4 formed in the joint T are communicatingly connected to each other,
wherein a functional component 5 which allows a fluid flowing between the fluid device
P and the joint T to pass through the functional component, and which exerts an action
on the fluid is interposed between the peripheral portion 3 and the joint T in a state
where the functional component is sealed both by the peripheral portion 3 and the
joint T, and an annular groove 6 and annular projection 7 which are fitted to each
other to constitute a sealing portion Sm in a state where the fluid device P and the
joint T are fittingly coupled to each other are formed in the fluid device P and the
